- Abstract
Background: Breast cancer is a heterogeneous condition with variations in histopathological, genomic, and biological characteristics. Although clinicopathological prognostic factors and gene expression profiles are commonly used to guide treatment decisions in patients with breast cancer, there is still a need for new prognostic markers. One potential marker is survivin, a protein belonging to the apoptosis inhibitor family. However, studies examining the relationship between survivin and prognosis in breast cancer have yielded inconsistent results. This study aimed to evaluate the impact of survivin expression on the prognosis of breast cancer patients through a meta-analysis., Methods: Studies evaluating survivin expression were sourced from the PubMed, Embase, and Cochrane databases. We conducted a meta-analysis based on full-text articles that evaluated the relationship between survivin expression and survival by immunochemistry or polymerase chain reaction. The studies were initially divided into 2 groups based on the evaluation of overall survival (OS) and disease-free survival (DFS). Subsequently, each group was further categorized according to the method used to detect survivin expression. Statistical analyses for this study were conducted using Stata and JAMOVI., Results: After screening with keywords, we identified 24 retrospective studies evaluating OS and 15 retrospective studies evaluating DFS, which were included in the analysis. We found that the studies in the meta-analysis were not heterogeneous, and this remained consistent when categorizing the groups by survivin expression detection. Survivin expression was associated with OS (HR 1.23, 95% CI 0.81-1.65) and DFS (HR 0.89, CI 0.42-1.36), indicating poor prognosis. This significant relationship between survivin expression and survival persisted when the studies were categorized by the detection method, either immunohistochemistry or polymerase chain reaction., Conclusion: In this study, we evaluated the prognostic significance of survivin expression in patients with breast cancer through a meta-analysis. These results support the use of survivin expression as a prognostic marker in breast cancer, potentially guiding treatment decisions., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2024 the Author(s).

- Abstract
Aims: Individuals with a higher De Ritis ratio (aspartate transaminase/alanine transaminase) and neutrophil-to-lymphocyte ratio (NLR) have an inferior survival in varied malignancies. To our knowledge, the prognostic potential of the De Ritis ratio and NLR to predict the survival in nonmetastatic glioblastoma multiforme (GBM) patients remains unclear. In this study, we aimed to explore the prognostic power of the De Ritis ratio and NLR in patients with nonmetastatic glioblastoma multiforme., Methods: Data of 262 patients with glioblastoma multiforme have been retrospectively analyzed. Their age, gender, tumor characteristics, AST/ALT ratio, NLR and hemogram values, including age at diagnosis and date of diagnosis were recorded., Results: The median survival time of the study group was 21 months (95% CI: 19‒23 months). The first-year and second-year survival rates were 73.0% and 40.5%, respectively. The univariate analysis revealed that the correlation of survival with age, gender, left/right location of tumor, mean platelet volume and De Ritis ratio did not reach the level of significance. The univariate analysis of the prognostic potential of NLR indicated that a 1-unit increase in NLR value translates to a 1.05 times higher risk of death (95% CI: 1.01‒1.09)., Conclusion: The results of this study lead to the observation that NLR value can serve as an effective prognostic marker in predicting the outcomes of patients with glioblastoma multiforme. It can be positioned as an easily accessible and cost-effective biomarker for establishing appropriate therapeutic strategies (Tab. 2, Fig. 1, Ref. 20).

- Abstract
Objective: The Hemoglobin, Albumin, Lymphocyte, and Platelet (HALP) Score and the Geriatric Nutrition Risk Index (GNRI) are used as prognostic factors in different types of cancers. In this study we analyzed the prognostic value of the HALP Score and the GNRI calculated prior to first-line treatment in patients diagnosed with de novo metastatic non-small cell lung cancer (mNSCLC)., Materials and Methods: De novo mNSCLC patients were retrospectively evaluated from January 2016 to December 2019. Patients with Driver's mutation, severe comorbidities, active infection, or insufficient organ function, and those receiving anti-inflammatory treatment were excluded from the study. Optimal cut-off points for the HALP score and the GNRI were calculated with the receiver operating characteristic (ROC) curve analysis. Predictive factors for overall survival (OS) were assessed with univariate and multivariate Cox proportional hazard analyses, and OS was studied with the Kaplan-Meier analysis., Results: The study included 401 patients in total. In the ROC curve analysis, the cut-off points were found 23.24 (AUC = 0.928; 95% CI: 0.901-0.955, p < 0.001) for HALP, and 53.60 (AUC = 0.932; 95% CI: 0.908-0.955, p < 0.001) for GNRI. Groups with lower HALP scores and lower GNRI had significantly shorter OS compared to those with higher HALP scores and GNRIs. Univariate analysis showed that male gender, smoking, high ECOG score, low HALP score and low GNRI were associated with worse survival rates. Multivariate analysis showed that low HALP score (HR = 2.988, 95% CI: 2.065-4.324, p < 0.001); low GNRI score (HR = 2.901, 95% CI: 2.045-4.114, p < 0.001) and smoking history (HR = 1.447, 95% CI: 1.046-2.001, p = 0.025) were independent factors associated with worse OS rates., Conclusion: Our study showed the HALP score and the GNRI to be of prognostic value as simple, cost-effective, and useful markers that predict OS in de novo mNSCLC patients., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Güç, Alacacıoğlu, Kalender, Oflazoğlu, Ünal, Yıldız, Salman, Küçükzeybek and Tarhan.)

- Abstract
Aim: Sarcopenia is a progressive and generalized syndrome that can be linked to many causes such as cancers, and is caused by a quantitative and qualitative disorder (loss of muscle strength and/or physical performance) of skeletal muscle mass. Although sarcopenia has some hypothetical explanation in clinical practice, the mechanisms underlying this condition have not been clearly differentiated in patients with cancer. We aimed to investigate the relationship between irisin, FGF21 and CRP in detecting sarcopenia in colorectal cancer patients., Material and Methods: Current prospectively study included non-metastatic newly diagnosed colorectal cancer patients. Patients were divided into 2 groups of 25 people, those with and without sarcopenia. Body composition measurements by examined by BIA. To measure the level of iris and FGF21 from patients, blood samples were taken into the biochemistry tube and their levels were measured., Results: The median age of the patients included in the study was 60 years (range: 21-81), 68% were men. It was found that there was a significant relationship between sarcopenia and gender and BMI measurement. When Spearman correlation analysis was performed between skeletal muscle mass index and FGF21, irisin and CRP, there was a positive correlation between skeletal muscle mass index and irisin and FGF21, while there was a negative correlation between skeletal muscle mass index and CRP. [respectively: (r: 0.282, p: 0.048), (r: 0.564, p: < 0.001) and (r: - 0.360, p: 0.010)]. Similar results were found between hand-grip strength and FGF21, irisin and CRP. [respectively: (r: 0.342, p: 0.015), (r: 0.290, p: 0.041) and (r: - 0.476, p < 0.001)]. When sarcopenia was treated as the dependent variable in the logistic regression analysis, and FGF21, irisin, CRP, gender and BMI were treated as the independent variables, irisin and CRP levels were determined as independent predictors., Conclusion: This study was revealed that there is a negative relationship between sarcopenia and irisin and FGF-21 in operated non-metastatic colorectal cancer patients and there may be a relationship between sarcopenia and inflammation. It suggests that these biomarkers may play a role in the pathophysiology of sarcopenia. However, our results need to be validated in different types of cancer and with more patients., (© 2022.

- Abstract
Objective: In this study, we aimed to assess anxiety and sleep quality in cancer patients treated or followed up at our clinic at the time of the outbreak of the COVID-19 pandemic., Methods: Seven hundred and sixty-one patients who were either treated or followed up at our oncology clinic between April 2020 and May 2020 were included. Patients were assessed with the State-Trait Anxiety Inventory (STAI) and the Pittsburgh Sleep Quality Index (PSQI)., Results: Mean scores of the 761 participants were STAI, 43.45 ± 9.34 (range, 23-75), and PSQI, 5.67 ± 4.24 (range, 0-19). Quality of sleep was found bad in 447 (58.7%) (global score ≥5). Univariate analyses demonstrated statistical differences by stage of cancer, status of treatment, subgroup of treatment, monthly income, and levels of education in anxiety and sleep quality levels. Multivariate analyses showed active treatment (OR: 21.4; 95% CI: 9.08-50.4; p < 0.001) as the major independent variable that affected sleep quality; the major independent variable associated with anxiety was low income (OR: 4.43; 95% CI: 1.69-11.5; p = 0.002)., Conclusion: Anxiety and sleep quality levels were found comparable to pre-pandemic reports, and the pandemic was not observed to have additional negative impact on cancer patients. Also, universal basal anxiety and sleep disorder that accompany cancer or active treatment were observed in our study. The accurate effects of the pandemic can be analyzed in further studies using repeated data obtained from the same patient group., (© 2021 S. Karger AG, Basel.)

- Abstract
Introduction: Although the chemotherapy-induced sarcopenia has some explanatory presence in clinical practice, the mechanisms underlying this phenomenon have not been clearly distinguished in patients with cancer. Therefore, we aimed with this study to investigate the role of inflammation by examining the inflammatory markers in the physiopathology of adjuvant chemotherapy-induced sarcopenia in patients with gastrointestinal tract cancer., Material and Method: To detect the presence of sarcopenia, patients' body composition measurements were assessed using the BIA, and their muscular strength was assessed with a handgrip dynamometer in both pre- and post-adjuvant chemotherapy. At the same time, we examined the baseline and post-adjuvant chemotherapy anthropometric measurements and inflammatory markers in serum (Hs-CRP, IL8, and TNF-α). Patients were divided in three groups. Group 1 consisted of patients who presented post-treatment sarcopenia although they did not have it prior to the treatment, group 2 included the patients who had no pre- or post-treatment sarcopenia, and group 3 was comprised of patients who presented pre-treatment sarcopenia. Each group included 30 patients., Results: A total of 90 patients were included in the study. Fifty-one of them were female patients. Median age was 60.5 (range 27-83). The patients consisted of cases with colorectal and gastric cancers. In group 1, Wilcoxon signed-rank test revealed a significant difference between scores of IL-8 (pg/mL), TNF-α (pg/mL) and Hs-CRP (mg/dL) given for the post-chemotherapy compared with the pre-chemotherapy ((Z 3.61, p < 0.001), (Z 3.254, p = 0.001), (Z 3.319, p = 0.001)). The post-chemotherapy median scores of IL-8 (pg/mL), TNF-α (pg/mL), and Hs-CRP were 76.31, 7.34, and 1.55, respectively, which remained on the levels of 12.25, 1.6, and 0.51 for the pre-chemotherapy. For group 2, a Wilcoxon signed-rank test indicated no significant difference between scores of the same markers given for the post-chemotherapy compared with the pre-chemotherapy. In all patients (including groups 1, 2, and 3), a comparison of the patients with pre-treatment sarcopenia (n = 30) and non-sarcopenic patients (n = 60) in terms of baseline IL-8, TNF-α, and Hs-CRP mean levels, IL-8 and Hs-CRP were found to be statistically different (146.02 (SD 311.96) vs. 47.24 (SD 66.3) (p = 0.009), 3.91 (SD 4.26) vs. 0.75 (SD 1.08) (p < 0.001), respectively)., Conclusions: The present prospective observational study suggested an association of chemotherapy-induced sarcopenia with inflammatory markers Hs-CRP, IL8, and TNF-α. Inflammation may play a role in chemotherapy-induced sarcopenia in newly diagnosed non-metastatic patients.

- Abstract
Background: Sarcopenia is associated with physical disability, increased post-operative complications, poorer tolerance to chemotherapy, and reduced survival outcome. However, little is known about the changes in body composition during chemotherapy treatment. We aimed to determine whether adjuvant or palliative chemotherapy causes the development of sarcopenia in newly diagnosed cancer patients and to reveal the relationship of sarcopenia with the duration of chemotherapy., Methods: The study included newly diagnosed cancer patients who underwent curative surgery for primary tumor and also cancer patients who were metastatic at diagnosis. Body composition and handgrip strength were assessed by bio-electric impedance analysis (BIA) and handgrip dynamometer tools, respectively. Measurement tests were performed prior to chemotherapy, in the third and sixth months of chemotherapy., Results: The median age of a total of 276 patients was 57.5 years (range 18-83), and majority of them (55.8%) were women. Among the pre-chemotherapy factors that could be associated with sarcopenia, male gender ≥ 65 years of age, body mass ındex (BMI) < 25, and nutritional risk screening 2002 score < 3 were found to be positively associated with sarcopenia (p < 0.001, p = 0.036, p < 0.001, and p < 0.001, respectively). In the multivariate analysis, male gender (p < 0.001) and BMI < 25 (p = 0.047) were found to be significant. Of 276 patients, 14.5% were sarcopenic prior to chemotherapy. After chemotherapy, 21.4% of them were sarcopenic at the end of the third month and 23.9% were sarcopenic at the end of the sixth month., Conclusion: The incidence of sarcopenia was found to be increased with chemotherapy itself and its duration in both non-metastatic and metastatic cancer patients which has to be evaluated in detail in disease-specific prospective and randomized studies.

- Abstract
Background: Adjuvant treatment is necessary in pancreatic cancer patients, but the optimal approach is not clear yet. Our aim was to explore the effectiveness of adjuvant treatment modalities in patients with operated pancreatic cancer., Methods: There were five groups of patients operated for primary pancreas adenocarcinoma. The first two groups included patients who were treated with only adjuvant chemotherapy or radiotherapy. The patients in third group had received combination chemotherapy and radiotherapy either sequentially or concomitantly. The fourth group was composed of patients who were treated with adjuvant chemotherapy after concurrent chemoradiotherapy, whereas the patients in the fifth group were only observed after surgery without any adjuvant treatment., Results: There were 83 operated pancreatic cancer patients available for analysis. Median age of the patients was 63 years (range, 40-82 years). There were 55 patients who had local disease recurrence (n = 14) or metastasis (n = 41) during or after adjuvant treatment. The median overall survival for all patients was 14 months. When we compared the median survival of patients who had any adjuvant treatment with the patients treated without any adjuvant therapy, we found a significant statistical difference between the groups (32.4 vs 6.5 months; P = 0.000). In addition, survival of each treatment group was also compared with each other but we did not find any significant statistical difference., Conclusions: Our result suggests that any adjuvant therapy in the treatment of pancreatic cancer patients is important. However, we could not find any superiority between adjuvant treatment modalities., Competing Interests: None

- Abstract
Purpose: Galectin-1 is a lectin involved in the carcinogenesis of many cancers. In the present study, we aimed to investigate the importance of galectin-1 in breast cancer carcinogenesis and its relationship with tumor development., Methods: Patients who were diagnosed with new breast cancer and a healthy volunteer population were included in the study. Preoperative and postoperative (1 month following visit at the medical oncology outpatient clinic) serum samples were collected from breast cancer patients and the healthy volunteer control group., Results: There was no statistically significant difference between patients' age, height, weight and body mass index (BMI) (p>0.05). The mean galectin-1 value of the preoperative group was 2.16±0.69 ng/ml, in the postoperative group; 1.75±0.31 ng/ml, and the healthy control group 1.64±0.40 ng/ml. A comparison of mean galectin-1 values between the groups showed that the highest galectin-1 level was found in the preoperative patients. When the mean serum galectin-1 levels of preoperative and postoperative patients were compared, a statistically significant difference was found between the two groups (p<0.001). Furthermore, a comparison of the control group and preoperative patients also revealed a statistically significant difference between the groups (p<0.001). When the control group and postoperative patients were compared, no statistically significant difference was found between them (p=0.16)., Conclusion: Serum galectin-1 levels were higher in breast cancer patients than in the healthy control group. In addition, postoperative galectin-1 levels of breast cancer patients tended to decrease. This suggests that serum galectin-1 levels are important in breast carcinogenesis and positively correlated with the presence of tumors.

- Abstract
Purpose: We aimed to investigate the prognostic significance of neutrophil/lymphocyte ratio (NLR), an indirect indicator for the immune response and AST/ALT ratio (De Ritis), liver enzymes that are commonly used in various clinical fields, in patients with advanced-stage pancreatic cancer., Methods: NLR and De Ritis of the patients with diagnosis of locally advanced and metastatic pancreatic cancer between the 2010-2017 were evaluated retrospectively. All patients were divided into two groups as high and low according to NLR and De Ritis cut-off values which were 2.4 and 0.75, respectively., Results: A total of 191 patients were evaluated. The mean overall survival (OS) in patients with NLR<2.4 at the time of diagnosis was 10±0.8 months, while it was 4±0.49 months in patients with NLR>2.4 (p<0.0001). The mean OS of the patients with a De Ritis <0.75 was 8±1.2 months, whereas the survival of those with De Ritis >0.75 was 6±0.74 months (p=0.024). The mean progression free survival (PFS) in patients with NLR<2.4 and De Ritis <0.75 at diagnosis were 5±0.76 months and 6±0.87 months respectively, whilst it was 3±0.37 months in patients with NLR>2.4 (p=0.017) and 4±0.3 months in patients with De Ritis >0.75 (p=0.14)., Conclusions: The NLR and De Ritis are associated with prognosis in many cancers and have been found to be associated with survival outcome in advanced-stage pancreatic cancer patients.

- Abstract
Purpose: Mesothelin is a cell surface glycoprotein which is highly expressed in various types of epithelial cancers. Its expression level is associated with poor prognosis in many cancer types. The aim this study was to evaluate the association of the level of mesothelin expression with clinicopathological characteristics and its prognostic significance in patients with advanced serous ovarian cancer (SOC)., Methods: Tissue blocks from a total 42 patients with advanced SOC treated at the medical oncology clinic of Izmir Katip Celebi University Ataturk Training and Research Hospital between 2006 and 2013 were evaluated. Immunohistochemical staining for mesothelin was performed. Clinical characteristics, optimal or suboptimal operation, response to platinum-based chemotherapy, and overall survival (OS) were analyzed., Results: The cut-off value of 45 for mesothelin H-score determined by ROC analysis predicted survival with 86% sensitivity and 75% specificity (p=0.020). We found a notable negative correlation between mesothelin H-score and OS (r = -0.570, p=0.0001). The median OS was 67 months (95%CI, 36.114 to 97.886) in the low-staining mesothelin H-score group and 27 months (95%CI, 22.238 to 31.762) in the high-staining mesothelin H-score group (p=0.002). Univariate analysis showed that the clinical stage IV disease (p=0.023), platinum chemoresistance (p=0.001), higher mesothelin H-score (p=0.002), and suboptimal surgery (p=0.024) were associated with worse OS. In the multivariate Cox regression model, mesothelin H-score (B=1.15, 95%CI=1.016 to 9.850, p=0.047) and the status of platinum sensitivity (B=-.916, 95%CI=.185 to -.864, p=0.020 were statistically significant predictors for OS., Conclusion: These results indicated that high mesothelin H-scores were significantly associated with poor prognosis in patients with advanced SOC.

- Abstract
Background: Mean platelet volume (MPV) is a parameter that increases during thrombotic and cardiovascular events. Tamoxifen (Tmx) and aromatase inhibitors (AIs), which are adjuvant endocrine therapies, may cause serious side effects, such as vascular thrombosis. The present study investigated the changes in MPV values of breast cancer patients receiving long-term adjuvant hormone therapy and the relationship of MPV with adverse effects of hormonotherapy., Methods: Data of 261 patients who had pathologically confirmed estrogen or progesterone receptor positive invasive breast cancer and had received hormonotherapy for at least a 5-year period were retrospectively analyzed. MPV levels were measured at baseline and at the first and fifth year of hormone therapy., Results: All patients were females and their median age was 50 years (range, 27-78 years). The mean MPV value was significantly increased in all patients in the Tmx, AI, and switch groups over time (p<0.001)., Conclusion: This is the first study evaluating the relationship between the 5-year adjuvant endocrine therapy and changes in MPV values in breast cancer patients. Monitoring changes in MPV values may be predictive for severe side effects in breast cancer patients receiving hormone therapy., Competing Interests: Conflict of interest Conflict of interest statement: Authors state no conflict of interest

- Abstract
Triple-negative breast cancer (TNBC) and HER2-positive breast cancer are more aggressive than other subtypes of breast cancer. Due to the limited number of treatment alternatives and the absence of target receptors in TNBC, and because of progression in the HER2-positive group despite targeted treatments, new treatment targets and therapeutic combinations are required. In this context, the present study aims to evaluate the prognostic importance of immunohistochemical androgen receptor (AR) expression in HER2-positive breast cancer and TNBC subtypes. AR nuclear staining density was evaluated immunohistochemically. A total of 111 operated patients with breast cancer were included in the study; 44 (39.6%) belonged to the HER2-positive breast cancer subgroup and 67 (60.4%) belonged to the TNBC subgroup. AR expression was 34.3% and 79.5% in TNBC and HER2-positive groups, respectively. The 5-year overall survival (OS) was 76% and 58% for the group with an AR-expression > 7.5% and AR-expression < 7.5%, respectively, in the TNBC subgroup (p = 0.042). In the HER2-positive patient group, the subgroups characterised by an AR-expression > 7.5% and AR-expression < 7.5% had 5-year OS rates of 57.6% and 63.5%, respectively (p = 0.91). Including the assessment of AR expression in the routine pathological examination will contribute to our understanding of the relevance of AR in the biology and prognosis of breast cancer.

- Abstract
Purpose: The neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) have recently been evaluated in many cancers in prediction of survival outcomes. The purpose of this study was to investigate the impact of NLR and PLR on the prognosis of patients with epithelial ovarian cancer (EOC)., Materials and Methods: A total of 208 patients with EOC were included in the study. Hematological parameters and clinicopathological data during diagnosis were retrospectively evaluated. The cut-off values were determined by calculating receiver operating characteristic (ROC) curve analysis of the patients., Results: The median over-all survival (OS) of patients with low NLR was 69 months (95% CI, 43.0-94.9) whereas high NLR was 36 months (95% CI, 29.1-42.8). The median OS with low PLR patients was 76 months (95% CI, 46.4-105.5) and high PLR was 35 months (95% CI, 28.5-41.4). In serous tumors (70.7%), the median OS with low NLR and high NLR was 54 months (95% CI, 27.9-80.0) and 34 months (95% CI, 28.2-39.7), and for the median OS with low PLR and high PLR it was 51 months (95% CI, 2 1.2-80.7) and 35 months (95% CI, 27.8-42.1), respectively., Conclusion: The present findings showed that the high NLR and high PLR were associated with poor prognosis and these values are significantly remarkable in EOC patients.

- Abstract
Background: In early breast cancer patients, the effects of hormonal therapy (tamoxifen and aromatase inhibitors) on plasma fibroblast growth factor 21 (FGF-21), lipid levels and body composition have not yet been investigated. Therefore, we aimed to analyze the relationship between FGF-21 and body composition as well as the effects of tamoxifen and aromatase inhibitors on plasma lipid levels, FGF-21, and body composition., Methods: A total of 72 patients were treated with either tamoxifen or aromatase inhibitors due to their menopausal status after adjuvant radiotherapy. Each patient was followed-up over a period of 1 year. Changes in body composition and serum lipid profile, glucose and FGF-21 levels were evaluated. We recorded the type of hormonal therapy, body mass index, waist-to-hip ratio, lipid profile, and FGF-21 levels both at the beginning and after 12 months., Results: There was a statistically significant decrease in serum FGF-21 levels after 12 months of adjuvant endocrine therapy (46 ± 19.21 pg/ml vs. 30.99 ± 13.81 pg/ml, p< 0.001). Total body water (p< 0.001), serum glucose (p= 0.036) and triglyceride levels (p< 0.001) also exhibited a significant decrease. The decreases in total cholesterol and low-density lipoprotein were not statistically significant. Likewise, high-density lipoprotein increased after adjuvant endocrine therapy, although it did not reach statistical significance. The changes in body composition, glucose, lipid profile and FGF-21 were similar in tamoxifen and aromatase inhibitor groups. A positive correlation was found between basal weight, fat mass, fat-free mass and serum FGF-21 levels; however, the correlation was maintained only for the fat-free mass at the 12th month., Conclusion: As part of the present study, we suggest that both tamoxifen and aromatase inhibitors can reduce FGF-21 levels independently of body compositions, and these drugs can provide antihyperlipidemic, antidiabetic and cardio-protective effects. We also recommend that serum FGF-21 level can be utilized as a tumor biomarker in early-stage breast cancer and for monitoring purposes. FGF-21 levels may help physicians estimate prognosis, too. Further studies with larger populations may shed light on the role of FGF-21 in breast cancer.

- Abstract
Background: Several studies evaluating the prognostic factors of gastrointestinal and pancreatic neuroendocrine tumors (GEP-NETs) have been published. The neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) have been accepted as prognostic factors for cancer patients., Materials and Methods: This study included 132 patients diagnosed with GEP-NETs. Peripheral blood samples were collected before the pretreatment period., Results: NLR and PLR were increased as the grade increased in NETs. The embryonic origin analysis revealed higher NLR and PLR rates in NETs of foregut origin. NLR and PLR were also higher in pancreatic NET patients compared to the gastroenteric NET patients. Analysis of NETs by TNM indicated that an advanced stage was accompanied by significantly higher NLR and PLR. We found a strong negative correlation between progression-free survival and NLR and PLR., Conclusion: The study verified that NLR and PLR are simple laboratory findings that can be used to identify NETs with a worse outcome., (© 2016 S.

- Abstract
Background: A limited number of studies have been conducted on the effects of hormonal therapy with tamoxifen (TMX) or aromatase inhibitors (AIs) on plasma levels of leptin and adiponectin, as well as body composition in breast cancer (BC) patients. Therefore, we aimed to analyze the relationship between adipocytokines and body composition as well as the effects of TMX and AIs on plasma adiponectin, leptin, leptin/adiponectin ratio (LAR) and body composition., Methods: Patients were treated with either TMX or AI according to their menopausal status after adjuvant radiotherapy. Changes in body composition and serum leptin and adiponectin levels were evaluated. We recorded the type of hormonal therapy, BMI, waist/hip ratio (WHR), leptin and adiponectin levels at study entry, and after 6 and 12 months., Results: From baseline to the 6- and 12-month follow-ups, there were statistically significant increases in WHR (p = 0.003), fat mass (p = 0.041), and serum leptin (p < 0.001) and adiponectin levels (p < 0.001). The changes in body composition and serum leptin and adiponectin levels were similar in TMX and AI groups. A statistically significant decrease was found in total body water and LAR (p < 0.001). Although weight and body fat percentage increased, such increases were not statistically significant. A positive correlation was found between baseline BMI and serum leptin levels. This correlation was maintained at 6 and 12 months. The negative correlation found between serum adiponectin levels at baseline and baseline BMI did not last throughout the study., Conclusion: In this study, increased leptin and adiponectin levels and a decreased LAR were found in both AI and TMX groups. These changes might have occurred through both mechanisms of hormonal therapy and body composition changes. Therefore, AIs and TMX may exert their protective effects for BC patients by decreasing LAR rather than affecting leptin or adiponectin alone., (© 2015 S. Karger AG, Basel.)

- Abstract
Objective: Determination of psychological problems will shed light on the terms of solution and provide support to patients about these problems will ensure the patients' coherence to the treatment and will enhance the benefits they receive from treatment. In this study, we aimed to determine these psychosocial problems and the interactions with each other in colon cancer patients., Methods: In this study, 105 patients with colorectal cancer were included. The forms consist of sociodemographic features, Hospital Anxiety and Depression Scale, European Organization for Research on Treatment of Cancer Questionnaires Quality of Life-C30 and Golombok-Rust Inventory of Sexual Satisfaction questionnaires., Results: Male patients had significantly higher European Organization for Research on Treatment of Cancer Questionnaires Quality of Life-C30 function scales and global quality-of-life scores than female patients. Golombok-Rust Inventory of Sexual Satisfaction scores of female patients were significantly higher than that of male patients. European Organization for Research on Treatment of Cancer Questionnaires Quality of Life-C30 function scales and global quality-of-life scores of the patients with high depression scores were significantly lower, conversely symptom scale scores of the patients with high depression scores were significantly higher than that of the patients with low depression scores. Patients with low anxiety scores had significantly higher European Organization for Research on Treatment of Cancer Questionnaires Quality of Life-C30 function scales and global quality-of-life scores than the patients with high anxiety scores. Symptom scale scores of the patients with high anxiety scores were significantly higher than that of the patients with low anxiety scores. The scores of Golombok-Rust Inventory of Sexual Satisfaction except premature ejaculation and vaginismus were significantly higher in patients with high anxiety scores and a significant difference was determined in touch, avoidance and anorgasm., Conclusions: This study demonstrates that there is a significant association with anxiety/depression symptoms and quality-of-life scores, sexual dysfunction. Sexual dysfunction is significantly more common in patients with high anxiety and depression scores., (© The Author 2015. Published by Oxford University Press. All rights reserved.

- Abstract
Purpose: Mesothelin is a cell surface glycoprotein that is overexpressed in various malignancies. Recent studies have revealed that mesothelin plays an oncogenic role in tumor growth and drug resistance through the Wnt/NF-κB/PI3K/Akt signaling pathways. Herein, the expression of mesothelin in HER2-positive and triple-negative breast cancer (TNBC) has been correlated with prognosis., Methods: A total of 430 patients with breast cancer treated between 2006 and 2013 were retrospectively reviewed; of these, 123 cases were considered TNBC (n=71; 58%) or were positive for HER2 (n=52; 42%). Mesothelin expression was assessed by immunohistochemistry., Results: Of the patients with TNBC, 30 (42.3%) were positive for mesothelin expression, compared to only two (3.8%) of the HER2-positive cases. As most HER2-positive tumors were negative for mesothelin staining, statistical analysis was not performed. Median overall survival (OS) was 70.1 months for patients with TNBC, whereas median OS was 70.1 months, in the mesothelin-positive group and 74.5 months in mesothelin-negative group, respectively. Strong correlation was seen between mesothelin expression and tumor grade in patients with TNBC (P<0.005). In a multivariable Cox proportional hazards model, mesothelin expression was not independently associated with OS in patients with TNBC., Conclusions: Expression of mesothelin was observed in 42.3% of patients with TNBC and demonstrated a strong association with tumor grade. However, its expression was not correlated with prognosis., (Copyright © 2015 Elsevier Masson SAS. All rights reserved.)

- Abstract
Background: The neutrophil-to-lymphocyte ratio (NLR) is a strong predictor of mortality in patients with cancer. Similarly, a study in a large series has shown that the newly defined derived NLR (dNLR; neutrophil/leukocyte-lymphocyte ratio) also has prognostic value. The present study retrospectively evaluates the prognostic significance of NLR and dNLR in breast cancer., Methods: Hematological parameters and clinicopathological data during diagnosis were retrospectively recorded for 1,527 patients diagnosed with breast cancer at Izmir Katip Celebi University Ataturk Research and Training Hospital from January 2006 to December 2011. The cut-off values were determined by calculating the NLR and dNLR of the patients., Results: The cut-off values were determined as 4 and 2 for NLR and dNLR, respectively. The association between NLR and dNLR assessed by Spearman's rank correlation analysis was 0.935 (P < 0.001). There was a significant difference regarding disease free survival (DFS) and overall survival (OS) in patients with NLR <4 and NLR ≥4 (respectively, P < 0.00, P < 0.001). Similarly, there was a significant difference regarding DFS and OS in patients with dNLR <2 and dNLR ≥2 (respectively, P < 0.001, P < 0.001). Furthermore, NLR and dNLR demonstrated a significant association with the American Joint Committee on Cancer (AJCC) staging (P < 0.001). Assessment using the Cox proportional multivariate model showed that high NLR, pN, pT, luminal A-like, luminal B-like (HER2 positive), basal-like, and AJCC staging are independent prognostic factors., Discussion: NLR was shown to be better than dNLR in terms of predicting prognosis in patients with breast cancer. However, large prospective studies are required to further demonstrate the prognostic significance of these two values.

- Abstract
Background: Although adjuvant chemotherapy is a standard treatment in stage III colon cancer, its benefit is not as clear for stage II patients. In this retrospective analysis, we aimed to evaluate the survival of patients with low-risk stage II colon cancer, the efficacy of adjuvant chemotherapy in high-risk stage II colon cancer patients, and prognostic factors in stage II disease., Materials and Methods: One hundred and seventeen patients who were diagnosed with stage II colon cancer between January 2006 and December 2011 were included in the study. Patients were stratified into two groups as being low-risk and high-risk according to risk factors for stage II disease. Adjuvant 5-fluorouracil-based chemotherapy were administered to the patients with risk factors., Results: Ninety-four patients were treated with adjuvant chemotherapy due to high risk factors and 23 were monitored without treatment. Median follow-up time was 43 months. In terms of disease free survival and overall survival, adjuvant chemotherapy did not provide a statistically significant difference. Univariate analysis demonstrated that bowel obstruction was the major risk factor for shortened disease-free survival, while bowel perforation and perineural invasion were both negative prognostic factors for overall survival., Conclusions: The recommendation of adjuvant chemotherapy for stage II colon cancer is not clear. In our study, it was found that adjuvant chemotherapy did not contribute to survival in high-risk stage II patients. Due to the fact that prognosis of stage II patients is good, many more patients will be needed for statistically significant differences in survival. Adjuvant chemotherapy containing 5 fluorouracil is being used to high-risk stage II patients although it is not a standard treatment approach.

- Abstract
Purpose: In this study, we investigated the effect of lapatinib plus capecitabine treatment in HER2-positive breast cancer patients with brain metastasis., Methods: Of 405 metastatic breast cancer patients with brain metastases at referral centers in Turkey, 46 were treated with lapatinib plus capecitabine only after the development of brain metastasis. Patients who only received trastuzumab-based therapy after the development of brain metastases were accepted as the historic control group for survival analyses (n = 65). Patients who received both drugs consecutively or sequentially were excluded from the analyses (n = 34)., Results: Median age among 46 patients who received lapatinib plus capecitabine therapy was 45 years (27-76), and median time for development of brain metastases was 11.9 months (0-69 months). Twenty-six out of 38 patients who received lapatinib plus capecitabine and had extracranial metastasis showed partial response or stable diseases (68.4 %). Grade 3-4 toxicity was observed in eight patients (17.3 %). Median overall survival (OS) in patients treated with lapatinib plus capecitabine was significantly increased compared to that in patients treated with trastuzumab-based therapy (19.1 vs. 12 months, respectively, p = 0.039). The incidence of cerebral death was slightly decreased in patients who received lapatinib plus capecitabine compared to those who received trastuzumab-based therapy (32 vs. 43.4 %, p = 0.332). In the multivariate analysis, lapatinib plus capecitabine therapy remained an independent positive predictor for survival [odds ratio (OR), 0.57; p = 0.02]., Discussion: Although this retrospective multicenter study had several limitations, the results suggest that undergoing lapatinib plus capecitabine therapy after the diagnosis of brain metastasis may further improve survival compared to undergoing only trastuzumab-based therapy.

- Abstract
Background: Bone marrow biopsy is widely used method for diagnosis, follow-up and staging of hemato-oncologic diseases. This procedure is also used for determining the bone marrow metastasis in patients with solid tumors. In this study, clinical, hematological, and pathological features of 58 patients with bone marrow metastases diagnosed by bone marrow biopsies were examined retrospectively, Materials and Methods: Among 3345 bone marrow biopsies performed in our hospital between January 2006 and August 2013, 58 cases with solid tumor metastasized to bone marrow were included in this study., Results: Among 58 cases with solid organ carcinoma metastasis in bone marrow, mean age was 59.9. Thirty-nine cases were found to have a known primary tumor focus. The most common tumors metastasized to bone marrow were breast carcinomas (23 patients, 59%), gastric carcinomas (6 patients, 15.3%), prostate carcinomas (4 patients, 10,2%), and lung carcinomas (3 patients, 7.7%), respectively. Nineteen patients were firstly diagnosed from bone marrow biopsies as metastatic carcinomas. The median overall survival after bone marrow metastasis was 28 days (95% confidence interval: 7.5-48.4). The median overall survival difference was not statistically significant between patients with primary known and unknown tumor (P = 0.973). Statistically significant difference was observed between the survival of breast cancer and gastric cancer (P = 0.028). The most common hematologic symptom was the coexistence of anemia and thrombocytopenia (31%), thrombocytopenia (27.6%) and anemia (20.7%) alone. The median overall survival difference was statistically significant between patients who have anemia and thrombocytopenia (P < 0.005)., Conclusion: Bone marrow biopsy is an easily accessible, easily applied, a useful procedure for diagnosing metastatic diseases in patients with hematologic symptoms such as anemia and thrombocytopenia besides being an uncomfortable procedure for patients. Furthermore, it is useful in predicting the prognosis and short survey after diagnosing bone marrow metastasis.

- Abstract
We aimed to investigate anxiety, depression and sexual satisfaction levels of testicular cancer survivors (TCSs) and compare the scores with healthy men's. The Hospital Anxiety and Depression Scale (HADS), Golombok-Rust Inventory of Sexual Satisfaction (GRISS) and European Organization for Research on Treatment of Cancer Questionnaires Quality of Life-C30 were used. Forty-one TCSs and thirty-eight healthy men were participated in this study. The total HADs scores of TCSs (12.21 ± 8.19) were less than the healthy group (14.44 ± 6.53; p > 0.05). The high depression scores rate was 29.2 and 55.2, and high anxiety scores rate was 24.4 and 28.9 for TCSs and healthy group, respectively. When we evaluated GRISS subscores and anxiety levels, we found significantly increase only in avoidance subscores in the TCSs (p = 0.04). When we evaluated GRISS subscores and depression levels, GRISS subscores of the TCSs who had high depression scores were also high. However, statistical significance was found in satisfaction (p = 0.009), touch (p = 0.04), avoidance (p = 0.01) and erectile dysfunction (p = 0.04) subscores in the TCSs. In the TCSs whose anxiety scores were high, emotional functioning (p = 0.009) and global QoL (p = 0.01) subscores of GRISS was found significantly low. In the TCSs whose depression scores were high, physical (p = 0.01), cognitive (p = 0.04), emotional (p = 0.03), social functioning (p = 0.02) and global QoL (p < 0.001) subscores of GRISS were found significantly low. Anxiety, depression and sexual satisfaction levels of TCSs were found to be similar with the control population.

- Abstract
Background and Objectives: We aimed to evaluate the prognostic value of cell cycle proteins and p53 together with clinicopathologic features in non-metastatic resected colon cancer., Methods: One hundred nine patients who were diagnosed with resected colon cancer between 2006 and 2011 were analyzed retrospectively. Immunohistochemical staining analyses were used to evaluate the expression of cyclins D1 and A, p53 and Ki-67 in tumor tissue., Results: High cyclin D1 and cyclin A expression was more common in stage II than stage III tumors. Disease recurrence was more frequent in tumors with low cyclin D1 expression (P = 0.05). No significant association was observed between p53, Ki-67 or cyclin A expression and the risk of relapse and/or death. Multivariate analysis showed that the strongest predictor for a shorter disease-free survival period was extracapsular nodal invasion (ECNI)., Conclusions: We were not able to establish a strong association between patient prognosis and cyclins D1 and A, p53 or Ki-67 expression. However, a negative correlation between cyclin D1 and cyclin A expression and disease stage as well as more frequent relapses in patients with low expression of cyclin D1 suggested that cyclins may be predictive for early relapse in non-metastatic colon cancer., (© 2014 Wiley Periodicals, Inc.)

- Abstract
In this study, we aimed to evaluate the clinicopathologic characteristics and prognosis of breast cancer (BC) patients with symptomatic bone marrow metastasis (BMM). Fifty-four BC patients, including patients with and without BMM, were evaluated retrospectively. In particular, the clinicopathologic features and survival of the patients with BMM (n = 27) were assessed and compared with the patients without BMM. All of the patients with BMM also had osseous metastases, and bone was the first site for distant recurrence in the majority of patients in the study group. Anemia was the most frequent symptom at presentation. The median time to BMM was 36.1 months (range 1.6-70.5 months, 95% CI). HER2(+) patients developed BMM earlier than HER2(-) patients (3.2 versus 38.3 months, 95% CI; p = 0.05). Patients with advanced disease at the time of initial BC diagnosis developed BMM earlier than patients with early disease (p = 0.04). Time to development of BMM was significantly shorter in tumors with perinodal infiltration (p = 0.001) and multicentric focus (p = 0.025). Median survival time after the diagnosis of apparent BMM was 6.43 months. Survival after BMM diagnosis in patients with grade III tumors was significantly shorter than in patients with grade I-II tumors (1.43 versus 5.36 months, 95% CI; p < 0.001). Systemic therapy after BMM diagnosis significantly prolonged survival (17.3 versus 0.93 months, 95% CI; p < 0.001). Hormone receptor-positive, high-grade, advanced-stage tumors at the time of initial BC diagnosis were more common in patients with BMM. Invasive lobular histology was also more frequent in patients with BMM. In conclusion, the presence of hormone receptor-positive, multicentric, grade III, advanced-stage tumors may be important risk factors for the development of evident BMM in BC patients. Systemic single-agent chemotherapy can prolong survival in these patients. However, multicenter analyses are required to verify these findings., (© 2014 Wiley Periodicals, Inc.)

- Abstract
Endothelin-1 (ET-1) and asymmetric dimethylarginine (ADMA) play a major role in tumor growth and metastasis. Our aim was to determine whether there is any association between these endothelial parameters and tumor markers with the clinical outcome of bevacizumab-treated metastatic colorectal cancer (mCRC) patients in terms of response and survival. Pretreatment serum levels of ET-1, ADMA, carcinoembryonic antigen (CEA), and carbohydrate antigen (CA) 19-9 were measured in 36 chemotherapy-naive mCRC patients treated with first-line bevacizumab-based therapy. Additionally, after first cycle of treatment, serum levels of these parameters were reanalyzed. Lower baseline serum ET-1 and ADMA levels were observed in patients responding to bevacizumab-based treatment (respectively, p = 0.037, p = 0.034). Median progression-free survival (PFS) (11 vs. 6 months, p = 0.012) and overall survival (OS) (28 vs 9 months; p = 0.007) were significantly shorter in patients with high pretreatment ET-1 levels. There was a significant decrease in ET-1 and CEA levels after first treatment (p = 0.020, p = 0.012), while ADMA and CA 19-9 levels were not significantly changed. Patients with decreased posttreatment ET-1 levels were shown to have inferior PFS (6 vs 11 months, p = 0.022), but no statistically significant difference was shown with respect to OS (p = 0.141). The effect of bevacizumab on endothelin axis including the biologic basis of decreasing ET-1 levels due to bevacizumab treatment and its association with inferior outcome has to be clarified in prospective trials.

- Abstract
Chordomas are rare neoplasms arising from notochordal remnants and may develop anywhere in the body while the most common anatomic site is the sacrococcygeal area. The most effective treatment of chordoma is surgery. Chordomas rarely metastasize to lung, bone, soft tissue, liver, lymph nodes, and skin. However, there is currently no standard systemic treatment for advanced stage chordoma. Here, we reported a rare presentation of chordoma patient with liver only metastases and poor prognosis.

- Abstract
Background: The purpose of this study was to analyze the predictive value of neutrophil/lymphocyte ratio (NLR) to better clarify which patient groups will benefit the most from particular treatments like bevacizumab., Materials and Methods: A total of 245 treatment-naive metastatic colorectal cancern (mCRC) patients were retrospectively enrolled and divided into 2 groups: 145 group A patients were treated with chemotherapy in combination with bevacizumab, and 100 group B patients were treated as above without bevacizumab., Results: Group A patients had better median overall survival (OS) and progression-free survival (PFS) (24.0 and 9.0 months) than group B patients (20 and 6.0 months) (p=0.033; p=0.015). In patients with low NLR, OS and PFS were significantly longer in group A patients (27 vs 18 months, p=0.001; 11 vs 7 months, p=0.017)., Conclusions: We conclude that NLR, a basal cancer related inflammation marker, is associated with the resistance to bevacizumab- based treatments in mCRC patients.

- Abstract
Purpose: We aimed to evaluate the effects of hormone receptor, HER2, and epidermal growth factor receptor (EGFR) expression on epithelial ovarian cancer (EOC) prognosis and investigate whether or not phenotypic subtypes might exist., Materials and Methods: The medical records of 82 patients who were diagnosed with EOC between 2003 and 2012 and treated by platinum-based chemotherapy were retrospectively evaluated. Expression of EGFR, oestrogen (ER), progesterone (PR), and cerbB2 (HER2) receptors were assessed immunohistochemically on paraffin-embedded tissues of these patients. Three phenotypic subtypes were defined according to ER, PR, and HER2 expression and associations of these with EGFR expression, clinicopathologic features, platinum sensitivity, and survival were investigated., Results: When we classified EOC patients into three subtypes, 63.4% had hormone receptor positive (HR(+)) (considering breast cancer subtypes, luminal A), 18.3% had triple negative, and 18.3% had HER2(+) disease. EGFR positivity was observed in 37 patients (45.1%) and was significantly more frequent with advanced disease (p=0.013). However, no significant association with other clinicopathologic features and platinum sensitivity was observed. HER2(+) patients had significantly poorer outcomes than HER2(-) counterparts (triple negative and HR positive patients) (p=0.019). Multivariate analysis demonstrated that the strongest risk factor for death was residual disease after primary surgery., Conclusions: Triple negative EOC may not be an aggressive phenotype as in breast cancer. The HER2 positive EOC has more aggressive behaviour compared to triple negative and HR(+) phenotypes. EGFR expression is more frequent in advanced tumours, but is not related with poorer outcome. Additional ovarian cancer molecular subtyping using gene expression analysis may provide more reliable data.

- Abstract
Background: The role of second-line therapy in metastatic pancreatic cancer is not clear. In this study, we aimed to explore the second-line efficiency of capecitabine and oxaliplatin (XELOX) in patients with advanced pancreatic cancer who have received gemcitabine-based first-line therapy., Materials and Methods: We retrospectively evaluated 47 patients with locally advanced or metastatic pancreatic cancer previously treated with gemcitabine-based first-line regimens. Treatment consisted of oxaliplatin 130 mg/m2 and capecitabine 1000 mg/m2 twice daily with a 3 week interval, until unacceptable toxicity or disease progression., Results: Median number of cycles was 4 (range, 2-10). The overall disease control rate was 38.3%. The median overall survival and progression-free survival from the start of second-line therapy were 23 weeks (95%CI: 16.6-29.5 weeks) and 12 weeks (95%CI: 9.8-14.4 weeks), respectively. The most common grade 3-4 toxicities were nausea, vomiting and hematologic side effects., Conclusions: Our result suggests that the combination of capecitabine and oxaliplatin was tolerated with manageable toxicity and showed encouraging activity as second-line treatment of advanced or metastatic pancreatic cancer patients with ECOG performance status 0-2.

- Abstract
Background: We aimed to investigate anxiety, depression and sexual satisfaction levels and the effects of depression and anxiety upon the sexual satisfaction of Turkish breast cancer patients and their partners., Materials and Methods: Data were collected from one hundred breast cancer patients and their partners, using three forms: one covering information about socio-demographic characteristics of the patients, the Hospital Anxiety and Depression Scale (HADs) and the Golombok-Rust Inventory of Sexual Satisfaction (GRISS)., Results: The frequencies, avoidance and touch subscores were statistically significantly high in the patients. Among those with high anxiety scores, the frequency, communication, satisfaction, touch, and anorgasmic subscale scores of GRISS were found to be significantly high. Among the partners whose anxiety scores were high, only the premature ejaculation subscale was statistically significant. It was determined that for partners with higher depression scores, the communication, satisfaction, avoidance, premature ejaculation and erectile dysfunction subscores of GRISS were statistically higher compared to partners with lower depression scores., Conclusions: Patients' quality of life may be increased by taking precautions to reduce their and their partners' psychosocial and psychosexual concerns.

- Abstract
This study aimed to investigate the prognostic and predictive effect of FOXP3+ Tregs together with clinicopathologic factors in locally advanced breast cancer (LABC) patients. The medical records of 101 LABC patients who received neoadjuvant chemotherapy (NAC) between 2005 and 2012 were evaluated retrospectively. The density of intratumoral FOXP3+ lymphocytes in paraffin-embedded tissues was assessed by immunohistochemical analyses in appropriate cases. The relationship with clinicopathologic features, prognosis and chemotherapy response was investigated. HR(-) and HER2(+) tumors tended to have higher pre-chemotherapy Tregs than HR(+) tumors, and significantly higher pathologic complete response (PCR) rates were observed in these patients. Treg decline after NAC was associated with better pathological response rates. Lower intratumoral infiltration of FOXP3+ Tregs after NAC (<3.4/HPF) was significantly associated with higher PCR rates for breast, and close to the significance limit for total (or both for breast and axillary) PCR rates (PCR for breast: 25 vs. 2.9 % for low vs. high Treg, p = 0.001; PCR for breast + axillary tissue: 13.9 vs. 0 %, p = 0.05). Despite better PCR rates, patients with high intratumoral Treg infiltrates (≥11.5/HPF) before chemotherapy had significantly shorter overall survival than patients with low Treg infiltrates (<11.5/HPF). Cox multivariate regression analyses demonstrated that the density of Treg infiltration before chemotherapy was the strongest predictor for survival. This study established the predictive and prognostic effect of intratumoral FOXP3+ Tregs in LABC patients. To predict clinical outcome, evaluation of FOXP3+ Tregs in tumoral tissues before and after NAC should be considered for these high-risk patients.

- Abstract
Background/aims: Sunitinib is a multi-targeted thyrosine kinase receptor inhibitor used in patients with advanced gastrointestinal stromal tumours (GISTs). We evaluated the efficacy and tolerability of sunitinib therapy in Turkish patients with GISTs., Methodology: Between January 2001 and April 2012, 57 patients who had progressive disease or experienced unacceptable toxicity during imatinib treatment from multiple centers were investigated retrospectively., Results: Thirty-three patients were male and 24 were female. The median age was 55 years (range; 16-84 years). Thirty-eight of the patients received imatinib for longer than 12 months, 13 patients received for 6-12 months, and 6 patients received for less than six months. The clinical benefit of sunitinib was 73.7%. Treatment-related adverse events were reported in 78% of the patients. Adverse events were generally mild to moderate in intensity. The median progression free survival (PFS) and overall survival (OS) of the patients that received sunitinib were 10.8 months and 23.9 months, respectively. The time of imatinib usage and response to sunitinib were independent prognostic factors for PFS and OS. Also, tumor size was an independent prognostic factor for PFS., Conclusions: Sunitinib is an effective treatment in Turkish patients with GISTs, with a clinical benefit of 73.7% and shows an acceptable tolerability.

- Abstract
Background: Cytotoxic chemotherapy is the basic treatment for metastatic gastric cancer. The "docetaxel, cisplatin, 5-day infusion of 5-FU (DCF5)" regimen is regarded as an effective therapy. However, the poor toxicity profile of this regimen and administration by 5-day infusion are major drawbacks of this method., Methods: Patients with measurable metastatic gastric carcinoma, Eastern Cooperative Oncology Group (ECOG) performance status ≤2, normal hematological and renal function, adequate hepatic function, and not pretreated for advanced disease with chemotherapy, received docetaxel on day 1, cisplatin on day 1, and 5-FU peripheral IV on day 1 (DCF1) every 3 weeks. The patients undergoing the DCF1 regimen could not receive the infusion regimen. This was a retrospective study about the use of DCF in 1 day in not previously treated metastatic gastric cancer., Results: In total, 95 patients were treated with a median of 5 cycles per patient. Those not previously treated for advanced disease received docetaxel 75 mg/m² on day 1, cisplatin 75 mg/m² on day 1, and 5-FU peripheral IV 750 mg/m²/day on day 1, plus filgrastim or lenograstim between days 3 and 7. Grade ≥3 toxicities were neutropenia (12%), anemia (11%), thrombocytopenia (3%), fatigue (18%), mucositis (10%), diarrhea (3%), nausea/vomiting (6%), neurological (3%), and palmar-plantar (2%). Two nonfatal febrile neutropenia episodes were recorded. There were no treatment-related deaths. In all patients with measurable disease, we observed an overall response rate of 46% (40 partial responses, 4 complete responses). Thirty-one patients (33%) had stable disease. The median overall survival was 9.0 months (95% CI 7.34-10.6)., Conclusions: Use of the DCF1 regimen in metastatic gastric cancer is feasible, with comparable activity to previous results achieved with epirubicin-based chemotherapy and infusion DCF in terms of overall survival. However, randomized and prospective studies need to be carried out with this regimen.

- Abstract
We aimed to define the clinicopathologic characteristics of breast cancer (BC) patients with brain metastasis (BM) and to investigate the effect of these parameters on survival. Seventy-nine patients diagnosed with BC and symptomatic BM between 1995 and 2011 were retrospectively evaluated. The relationship between clinicopathological features and outcome was investigated. Triple negative patients had the shortest overall survival (OS) while HR(+)HER2(-) patients had the longest (48.2 vs 88.2 months, 95 % CI; p = 0.33). Multivariate analysis demonstrated that luminal A subtype was the strongest positive predictor of prolonged OS (HR 0.48, 95 % CI 0.28-0.84; p = 0.01), while poor performance status (PS) (ECOG 3-4) at BM was the strongest predictor of shortened OS (HR 1.92, 95 % CI 1.21-3.06; p = 0.006). The patients with early-stage BC at diagnosis had BM later than the advanced-staged patients (47 months for Stage I-II disease, 23.2 months for Stage III-IV disease, 95 % CI; p = 0.002). Median survival after BM was 10.2 months (6.4-14 months, 95 % CI). The patients with liver or skin metastases had significantly shorter survival than the patients with only BM (4.8 vs 17 months, p < 0.001 for liver and 4.8 vs 11.1 months, p = 0.04 for skin). Multivariate analysis demonstrated that regardless of the BC subtype, lack of systemic therapy, and liver involvement were independent factors associated with increased risk of death (HR 4, 95 % CI 1.7-9.1; p = 0.001 and HR 2.2, 95 % CI 1.05-4.9; p = 0.036 respectively). Clinical outcome after BM mostly depends on the ECOG PS and the fact that whether the patient received systemic therapy or not. Systemic therapy prolongs survival especially in HER2 positive patients.

- Abstract
Epithelioid hemangioendothelioma is a rare, low-grade malignant vascular tumour. It is frequently seen in the liver, but can occur in the lungs, bones, and other soft tissues. Although survival time might be reasonable in cases that can undergo liver transplantation, there is no consensus on the treatment of metastatic patients. We report a 24-year-old female patient with rapidly progressing malignant epithelioid hemangioendothelioma that presented with acute abdominal distension. The patient was refractory to anthracycline and Interferon treatment and died 6.5 months after the diagnosis.

- Abstract
Neuroendocrine carcinoma is a relatively rare tumor and its coexistence with other primary cancers is very exceptional. We present a case of a 63-year-old woman with biliary obstruction due to a high-grade neuroendocrine carcinoma located in ampulla of Vater who was found to have a synchronous sigmoid colon adenocarcinoma while undergoing staging laparotomy and pancreas head resection. Medical history was significant only for basal cell skin cancer. Immunohistochemical examination revealed the concurrence of histologically proved neuroendocrine carcinoma (chromogranin A, synaptophysin, and CD56 were positive) and Stage II (T3, N0, and M0) according to the TNM staging classification of colorectal cancer. The coexistence of neuroendocrine tumors with either synchronous or metachronous unrelated cancer is increasingly recognized. The patients with neuroendocrine carcinoma should be evaluated for secondary primary malignancies.

- Abstract
Background: To evaluate the clinicopathologic and demographic characteristics of triple-negative breast cancer (TNBC) patients and to determine differences from non-triple-negative cases., Materials and Methods: A detailed review of the medical records of 882 breast cancer (BC) patients was conducted to obtain information regarding age, menopausal status, height and weight at the time of diagnosis, presence of diabetes or hypertension, and pathologic characteristics of the tumor (tumor size, lymph node status, histologic grade, ER status, PR status, HER2 status, p53 mutation). Body mass index (BMI) was calculated and a value of ≥30 was considered as indicative of obesity., Results: 14.9% (n=132) of the patients had TNBC. There was no difference among the patients in terms of median age, comorbid conditions and menopausal status. The proportion of medullary, tubular and mucinous carcinomas was significantly higher (15.9%) in the triple-negative (TN) group, while invasive lobular histology was more frequent (8.2%) among non-triple negative (NTN) cases (p<0.001). Grade 3 (G3) tumors were more frequent in the triple-negative group (p<0.001). The rate of p53 mutation was 44.3% in TN tumors versus 28.2% in the NTN group (p<0.001). The two groups were similar in terms of LN metastasis. In the NTN group, the rate of patients with BMI ≥30 was 53% among postmenopausal patients, while it was 36% among premenopausal women, and the difference was statistically significant (p<0.001). No significant difference was observed in terms of BMI between postmenopausal and premenopausal patients in the TN group (p=0.08)., Conclusions: TNBC rates and clinicopathologic characteristics of the Turkish patient population were consistent with the data from Europe and America. However, no relationship between obesity and TNBC was observed in our study. The association between TNBC and obesity needs to be evaluated in a larger patient population.

- Abstract
Background: Breast cancer is the second leading cancer causing death in women. Circulating tumor cells are among the prognostic factors while tumor markers are of diagnostic value and can be used for follow-up. The aim of this study was to investigate the correlation between the prognostic significance of the serum CA15-3 levels, number of circulating tumor cells and histopathological tumor factors., Materials and Methods: Thirty patients recently diagnosed with breast cancer were included in the study. Number of circulating tumor cells and serum CA15-3 level were assessed when metastasis was detected and diagnostic value was assessed. Presence of associations with estrogen and progesterone receptors, c-erbB2, Ki-67 proliferation index and histological grade were also evaluated., Results: Median overall survival of the patients with serum CA15-3 levels of >108 ng/dl was 19 months whereas for those with a low serum level it was 62 months. Median overall survival for CTC ≥5vs CTC<5 patients was 19 months and 40 months respectively. The difference between the two groups was statistically significant., Conclusions: Prognostic significance of the CTC count and CA15-3 levels in metastatic breast cancer patients was demonstrated.

- Abstract
Background: Long-term survival is a problem with locally advanced and metastatic renal cell carcinomas. Sunitinib malate is an oral multitargeted tyrosine kinase inhibitor, but data on sunitinib use as a second line treatment in metastatic renal cell carcinoma (mRCC) are limited. Prognostic and predictive value of peripheral blood markers has been shown for many cancers., Materials and Methods: Efficacy and safety profiles of sunitinib after interferon alpha were evaluated based on retrospective data for 23 patients with mRCC. Hematological parameters (neutrophils, lymphocytes, platelets, mean platelet volume, neutrophil/lymphocyte ratio, platelet/lymphocyte ratio) were recorded at the time of metastasis. It was evaluated whether hematological parameters were prognostic and predictive factors., Results: Median progression-free survival (PFS) time was 16.5 months (95%CI: 0-34.5). Median overall survival (OS) time was 25.7 months (95%CI: 10.8-40.0). Most common side effects were neutropenia (52.2%), stomatitis (26.1%) and hand-food syndrome (26.1%). PFS was found 3.13 vs 17.1 months in patients with neutrophil / lymphocyte ratio (NLR)>3 vs NLR≤3 (p:0.012). Median OS was 6.96 vs 27.1 months in patients with NLR>3 vs NLR≤3 (p:0.001).While 75% of patients who responded to sunitinib had NLR≤3, in 72% of patients with no response to sunitinib NLR>3 was detected (p:0.036). The association between the Memorial Sloan-Kettering Cancer Center (MSKCC) criteria and NLR was statistically significant (p:0.022)., Conclusions: Data on second line sunitinib treatment following cytokine in mRCC are limited. In our study, we observed second line sunitinib treatment following IFN-alpha to be effective and tolerable. NLR appeared to have prognostic and predictive value.

- Abstract
Background: It is well known that tumor-infiltrating lymphocytes (TIL) and, to a lesser extent, peripheral hematologic parameters from patients with cancer have to effect on prognosis. The aim of this study was to evaluate the effect of hematologic parameters and TIL on prognosis of patients with gastric cancer., Methods: 236 patients who had diagnosed as gastric adenocarcinoma. All hematologic parameters were noted at the time of diagnosis. The number of lymphocyte aggregates as well as the number of lymphocytes within these agregat was counted.The prognostic significance and correlations of high neutrophil-lymphocyte ratio (NLR) together with TIL, was evaluated by multivaried analysis., Results: The cut-off values of NLR and derived NLR (dNLR) were 3.8 and 2. The NLR was independently associated with survival (P < 0.001). dNLR was not independently associated with overall survival. No significant advantages for overall survival were found for the high TIL (p: 0.372). It was not determined correlation between TIL - NLR and TIL-lymphoid aggregate density (respectivly, P: 0.104; P: 0.246)., Conclusions: The results suggest that the elevated NLR predicts poor overall survival following at the time diagnosis for all stage gastric cancer. dNLR was not independently associated with overall survival. There is insufficient evidence to the assesment of TIL by a nonspesific method. Therefore further studies is required, to confirm our hypothesis in larger patient cohorts.

- Abstract
Background: To assess the efficacy and tolerability of Cisplatin plus Gemcitabine combination in patients with brain metastases (BM) from breast cancer (BC)., Materials and Methods: Eighteen BC patients with BM who were treated with Cisplatin plus Gemcitabine regimen between 2003-2011 were evaluated., Results: A median of 6 cycles of this regimen were received, in fifteen patients (83.3%) as first-line chemotherapy, in 2 as second- line and in 1 as third-line after diagnosis of BM. Dose reduction was performed in 11 (61.1%) patients; major reasons were neutropenia and leukopenia. Grade III neutropenia and Grade II trombocytopenia rates were 33.3% and 16.7% respectively. Overall response rate (ORR; complete+partial response rate) was 33.4% (n=6) for the entire study population; triple negative patients achieved an 66.6% ORR while hormone receptor (HR) positive patients had 25% and HER2 positive patients 12.5%. Median progression-free survival was 5.6 months (2.4-8.8 months, 95%CI) and longer in patients with triple negative breast cancer (TNBC) (median 7.4 months, 95%CI, 2.4-12.3 months) than the patients with other subtypes (median 5 months for HER2 positive and 3.6 months for HR positive patients). Median PFS of the patients with TNBC who received this regimen as first-line was 9.2 months (5.2-13.2 months, 95%CI)., Conclusions: Cisplatin plus Gemcitabine may be a treatment option for patients with BM from breast cancer. Longer PFS and higher response rates are results that support the usage of this regimen especially for the triple negative subtype. However, further prospective and randomized trials are clearly required to provide more exact information.

- Abstract
Background: To investigate the predictive and prognostic effects of clinicopathologic and immunohistochemical (IHC) features in patients with gastrointestinal stromal tumours (GISTs)., Materials and Methods: Fifty-six patients who were diagnosed with GIST between 2002 and 2012 were retrospectively evaluated. Relationships between clinicopathologic/immunohistochemical factors and prognosis were investigated., Results: Median overall survival (OS) of the whole study group was 74.9 months (42.8-107.1 months), while it was 95.2 months in resectable and 44.7 months in metastatic patients respectively (p=0.007). Epitheliolid tumor morphology was significantly associated with shortened OS as compared to other histologies (p=0.001). SMA(+) tumours were significantly correlated with low (<10/50HPF) mitotic activity (p=0.034). Moreover, SMA(+) patients tended to survive longer and had significantly longer disease-free survival (DFS) times than SMA (-) patients (37.7 months vs 15.9 months; p=0.002). High Ki-67 level (≥30%) was significantly associated with shorter OS (34 vs 95.2 months; 95%CI; p=0.001). CD34 (-) tumours were significantly associated with low proliferative tumours (Ki-67<%10) (p=0.026). Median PFS (progression-free survival) of the patients who received imatinib was 36 months (27.7-44.2 months). CD34 (-) patients had significantly longer PFS times than that of negative tumours; (50.8 vs 29.8 months; p=0.045). S100 and desmin expression did not play any role in predicting the prognosis of GISTs. Multivariate analysis demonstrated that ≥10/50HPF mitotic activity/HPF was the only independent factor for risk of death in GIST patients., Conclusions: Despite the negative prognostic and predictive effect of high Ki-67 and CD34 expression, mitotic activity remains the strongest prognostic factor in GIST patients. SMA positivity seems to affect GIST prognosis positively. However, large-scale, multicenter studies are required to provide supportive data for these findings.
